BBM abandoned its Historic Collection series this year to try something new. Perhaps they ran out of topics for the series; I liked the themes, which ranged from greatest sluggers or pitchers, to hometowns, to jersey numbers. However, execution has rarely been a strong point of BBM's card design department. Ballpark Stories was a missed opportunity to include cards of Japan's storied (and mostly undocumented) stadiums. And Memories of Uniform had photos where you couldn't see the uniform at all!
Time Travel 1975 looks back at players from the 1975 season through cardboard.
Japan Series teams Braves and Carp receive 12 cards each in the set, while other teams get six cards each.
Parallels of both Title Holders sets are available numbered to 200 and numbered to 50. They have a hologram foil effect, though I can't see any difference between the two versions yet other than serial numbering.
There are two formats of autographed cards randomly inserted. Horizontal signatures have 69 subjects, including Go Rangers and Iwasaki, with print runs between 25 and 90 (5539 total). The design has a retro feel, like the base set.
Fourteen signers have vertical autograph cards, with print runs of only 5-15 cards (185 total). These autographs are similar to the Title Holders inserts, with a modern feel.
I love the vintage card stock and concept of the Time Travel series. I like it so much that I have the mini-master set already. Add this to the list of BBM successes, and I hope it continues longer than BBM's last vintage-style run (the Achievement series, which was spread out over four team box sets).
